Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Betonteilen, insbesondere Kanalisationsbauteile, mit Kunststoffauskleidung, bei welchem ein flächiges Kunststoffteil mit über eine Fläche des Kunststoffteils vorstehenden Verankerungselementen zur Verankerung des Kunststoffteils an einem zugehörigen Betonteil versehen wird. The present invention relates to a method for producing concrete parts, in particular sewerage components, with plastic lining, in which a planar plastic part is provided with anchoring elements projecting over a surface of the plastic part for anchoring the plastic part to an associated concrete part.

Des weiteren betrifft die vorliegende Erfindung eine Vorrichtung zur Durchführung des Verfahrens. Furthermore, the present invention relates to a device for carrying out the method.

Betonteile werden oftmals mit Kunststoff ausgekleidet, um den Beton zu schützen, beispielsweise vor aggressiven Bestandteilen im Abwasser bei Betonrohren für die Kanalisation. So werden Schachtböden von Abwasserschächten mit Kunststoffplatten versehen. Um eine feste Verbindung zwischen den Kunststoffplatten und den aus Beton gefertigten Schachtböden zu erreichen, werden die Kunststoffplatten mit über ihre Oberfläche überstehenden Verankerungselementen versehen. Bei den Verankerungselementen kann es sich um Klötze oder Leisten handeln, die ebenfalls aus Kunststoff gefertigt sind. Die Verbindung der Verankerungselemente mit den Kunststoffplatten kann durch Kunststoffschweißen erfolgen, wofür die Verankerungselemente und/oder die Kunststoffplatte zumindest in ihrem Verbindungsbereich bis zum Schmelzen erwärmt und gegeneinander gepresst werden. Zumindest der aufzuschmelzende Teil besteht dementsprechend aus thermoplastischem Kunststoff. Das flächige Kunststoffteil muss nicht plattenförmig sein, sondern kann beliebige Form aufweisen, also bspw. auch die Form einer gekrümmten Fläche oder, insbesondere für die Auskleidung eines Betonrohres, die Form eines Rohres. Concrete parts are often lined with plastic to protect the concrete, for example from aggressive components in the wastewater in concrete pipes for sewage systems. Thus shaft bottoms of sewage shafts are provided with plastic plates. In order to achieve a firm connection between the plastic plates and the shaft bottoms made of concrete, the plastic plates are provided with anchoring elements projecting beyond their surface. The anchoring elements may be blocks or strips, which are also made of plastic. The connection of the anchoring elements with the plastic plates can be done by plastic welding, for which the anchoring elements and / or the plastic plate are heated to melting at least in their connection area and pressed against each other. At least the part to be melted accordingly consists of thermoplastic material. The sheet-like plastic part does not have to be plate-shaped, but may have any shape, that is, for example, the shape of a curved surface or, in particular for the lining of a concrete pipe, the shape of a pipe.

Der Erfindung liegt die Aufgabe zugrunde, ein einfaches und kostengünstiges Verfahren zur Herstellung der genannten Betonteile zur Verfügung zu stellen. The invention has for its object to provide a simple and inexpensive method for producing said concrete parts.

Diese Aufgabe wird dadurch gelöst, dass die Verankerungselemente mit dem Kunststoffteil verbunden werden, indem die Verankerungselemente jeweils auf die entsprechende Fläche des Kunststoffteils aufgesetzt, gegen das Kunststoffteil gepresst und so lange um eine zur Fläche des Kunststoffteils senkrechte Achse rotiert werden, bis das Kunststoffteil und/oder das Verankerungsteil an der Kontaktfläche zwischen beiden aufschmelzen, und dass dann das Verankerungsteil mindestens so lange stillgehalten wird, bis sich das aufgeschmolzene Material soweit verfestigt hat, dass das Verankerungsteil am Kunststoffteil hält. This object is achieved in that the anchoring elements are connected to the plastic part by the anchoring elements each placed on the corresponding surface of the plastic part, pressed against the plastic part and so long rotated about an axis perpendicular to the surface of the plastic part until the plastic part and / or melt the anchoring part at the contact surface between the two, and that then the anchoring part is held still at least until the molten material has solidified so far that the anchoring part holds on the plastic part.

Eine erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens ist gekennzeichnet durch eine motorisch angetriebene Spindel mit einem Werkzeug zum drehfesten Verbinden der Spindel mit einem Verankerungselement. A device according to the invention for carrying out the method is characterized by a motor-driven spindle with a tool for non-rotatably connecting the spindle to an anchoring element.

Durch das erfindungsgemäße Rotieren der gegen das Kunststoffteil gepressten Verankerungselemente können die Verankerungselemente und/oder das Kunststoffteil im Bereich ihrer Berührungsflächen aufgeschmolzen werden. Dadurch wird eine stoffflüssige Verbindung zwischen den Verankerungselementen und dem Kunststoffteil erzeugt, die nach Abkühlen und Verfestigen des aufgeschmolzenen Kunststoffs stabil ist. The inventive rotating of the pressed against the plastic part anchoring elements, the anchoring elements and / or the plastic part can be melted in the region of their contact surfaces. As a result, a fluid connection between the anchoring elements and the plastic part is produced, which is stable after cooling and solidification of the molten plastic.

Das erfindungsgemäße Verfahren hat insbesondere den Vorteil, dass die Herstellung maschinell erfolgen kann. Hierfür werden die Verankerungselemente mit einer motorisch angetriebenen Spindel verbunden. Die Spindel kann an einem Roboterarm angebracht sein, mit welchem die Verankerungselemente bei der Herstellung gehandhabt werden. Insbesondere können die Verankerungselemente durch den Roboter von einem Magazin entnommen und zur entsprechenden Position auf dem Kunststoffteil gebracht werden. Mit dem Roboter können die Verankerungselemente dann gegen das Kunststoffteil gepresst und rotiert werden, bis der Kunststoff schmilzt. The inventive method has the particular advantage that the production can be done by machine. For this purpose, the anchoring elements are connected to a motor-driven spindle. The spindle may be attached to a robot arm with which the anchoring elements are handled during manufacture. In particular, the anchoring elements can be removed by the robot from a magazine and brought to the corresponding position on the plastic part. With the robot, the anchoring elements can then be pressed against the plastic part and rotated until the plastic melts.

Bevorzugt ist es, wenn auch die Verankerungselemente aus Kunststoff, insbesondere thermoplastischem Kunststoff bestehen. Beim Rotieren werden dadurch nicht nur das Kunststoffteil, sondern die Verankerungselemente im Bereich ihrer Berührungsfläche aufgeschmolzen. Als geeigneter Kunststoff hat sich Polypropylen herausgestellt. It is preferred if the anchoring elements made of plastic, in particular thermoplastic consist. During rotation, not only the plastic part, but the anchoring elements are melted in the region of their contact surface. As a suitable plastic polypropylene has been found.

Bei den Verankerungselementen handelt es sich bevorzugt um Spritzgießteile, während das Kunststoffteil bevorzugt durch Tiefziehen hergestellt ist. Beide genannte Verfahren haben sich für den jeweiligen Einsatz als vorteilhaft herausgestellt. The anchoring elements are preferably injection molded parts, while the plastic part is preferably produced by deep drawing. Both methods have been found to be advantageous for the particular application.

Mit dem erfindungsgemäßen Verfahren können insbesondere Schachtböden und Schachtringe hergestellt werden. Auch mit Kunststoff ausgekleidete Abwasserrohre können mit dem erfindungsgemäßen Verfahren hergestellt werden. With the method according to the invention, in particular shaft bottoms and manhole rings can be produced. Plastic-lined sewage pipes can also be produced by the process according to the invention.

Eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens umfasst eine motorisch angetriebene Spindel mit einer Aufnahme für ein Verankerungselement. Die Spindel ist bevorzugt an einem Roboterarm angebracht. Die Vorrichtung umfasst bevorzugt ein Magazin zum Vorhalten von Verankerungselementen. An apparatus for carrying out the method according to the invention comprises a motor-driven spindle with a receptacle for an anchoring element. The spindle is preferably attached to a robot arm. The device preferably comprises a magazine for holding anchoring elements.

Das erfindungsgemäße Verfahren wird beispielhaft anhand der beigefügten Zeichnungen erläutert. Es zeigen, The inventive method will be explained by way of example with reference to the accompanying drawings. Show it,

1 ein Kunststoffteil mit aufgebrachten Verankerungselementen und ein Magazin mit noch nicht aufgebrachten Verankerungselementen, und 1 a plastic part with applied anchoring elements and a magazine with not yet applied anchoring elements, and

2 eine Ausschnittsvergrößerung gemäß Kreis A in 1. 2 an enlarged detail according to circle A in 1 ,

Das Kunststoffteil 1 ist in 1 als rechteckige Platte dargestellt. In der Praxis kann dieses Kunststoffteil eine beliebige Form aufweisen, beispielsweise die Form eines Schachtbodens mit Kreisform und rinnenförmigen Vertiefungen, aber auch die Form einer dreidimensionalen Fläche einschließlich eines Rohres. Die dargestellten Verankerungsteile 2 weisen eine konusartige Form mit einer kleineren unteren Abschlußscheibe 3 unter einer größeren oberen Abschlußscheibe 4 auf. Die kleinere Scheibe 3 ist zum Aufsetzen auf das Kunststoffteil 1 vorgesehen, während die größere Scheibe 4 auf ihrer Oberseite einen Schlitz 5 aufweist, in welchen ein Werkzeug 6 zum Rotieren des Verankerungsteils 2 eingreifen kann. Die schlitzförmige Aufnahme 5 kann auch bis in den konusförmigen mittleren Abschnitt 7 des Verankerungsteils 2 hineinreichen. The plastic part 1 is in 1 shown as a rectangular plate. In practice, this plastic part can have any shape, for example the shape of a shaft bottom with a circular shape and groove-shaped depressions, but also the shape of a three-dimensional surface including a tube. The illustrated anchoring parts 2 have a cone-like shape with a smaller lower lens 3 under a larger upper lens 4 on. The smaller disc 3 is for placing on the plastic part 1 provided while the larger disc 4 on its top a slot 5 in which a tool 6 for rotating the anchoring part 2 can intervene. The slot-shaped recording 5 can also reach into the cone-shaped middle section 7 of the anchoring part 2 extend.

Wie mit Pfeil 8 angedeutet, werden die Verankerungsteile 2 auf der Kunststoffplatte 1 rotiert. Hierfür wird das Werkzeug 6 in die Aufnahme einer motorisch angetriebenen Spindel eingesetzt. Beim Rotieren wird das Verankerungsteil 2 über das Werkzeug 6 gegen die Kunststoffplatte 1 gepresst. Dadurch wird ein schnelles Aufschmelzen der Kunststoffplatte 1 und/oder des Verankerungselementes 2 an ihrer Berührungsfläche erreicht. As with arrow 8th indicated, the anchoring parts 2 on the plastic plate 1 rotates. This is where the tool becomes 6 used in the recording of a motor-driven spindle. When rotating, the anchoring part becomes 2 about the tool 6 against the plastic plate 1 pressed. This will cause a rapid melting of the plastic sheet 1 and / or the anchoring element 2 reached at their contact surface.

Die Durchführung des erfindungsgemäßen Verfahrens erfolgt derart, dass jeweils ein Verankerungselement 2 aus einem Magazin 9 entnommen und mit dem Werkzeug 6 verbunden wird. Dann wird das Verankerungselement 2 an die gewünschte Stelle auf der Kunststoffplatte 1 aufgesetzt, gegen diese gedrückt und dabei durch die Spindel rotiert. Sobald der Kunststoff ausreichend aufgeschmolzen ist, wird die Spindel gestoppt und das Verankerungselement 2 so lange weiter gegen die Kunststoffplatte 1 gedrückt gehalten, bis der aufgeschmolzene Kunststoff durch Abkühlen wieder ausreichend verfestigt ist. Sodann wird das Werkzeug 6 von dem angebrachten Verankerungselement 2 gelöst und mit dem nächsten Verankerungsteil 2 aus dem Magazin 9 verbunden. The implementation of the method according to the invention is carried out such that in each case an anchoring element 2 from a magazine 9 taken and with the tool 6 is connected. Then the anchoring element 2 to the desired location on the plastic plate 1 put on, pressed against this while rotating through the spindle. Once the plastic has melted sufficiently, the spindle is stopped and the anchoring element 2 so long against the plastic plate 1 kept pressed until the molten plastic is sufficiently solidified by cooling again. Then the tool 6 from the attached anchoring element 2 solved and with the next anchoring part 2 from the magazine 9 connected.

Auf diese Weise werden so viele Verankerungselemente wie gewünscht an der Kunststoffplatte 1 angebracht. Die Seite des Kunststoffteils 1 mit den Verankerungselementen 2 ist die dem Betonteil zugewandte Seite. Bei der weiteren Herstellung wird dann auf diese Seite Beton gegossen, welcher die Verankerungselemente umfließt und nach Aushärten dadurch an der Kunststoffplatte 1 verankert ist. Die Verankerungselemente 2 bilden quasi Hinterschnitte, welche für eine Formschlussverbindung zwischen dem Beton und der Kunststoffplatte 1 sorgen. Damit ist eine feste Verbindung des Kunststoffteils 1 mit dem Betonteil gewährleistet. In this way, as many anchoring elements as desired on the plastic plate 1 appropriate. The side of the plastic part 1 with the anchoring elements 2 is the side facing the concrete part. In the further production of concrete is then cast on this side, which flows around the anchoring elements and after curing by the plastic plate 1 is anchored.
